CONSTRUCTION OF WAGONS.

Application filed June 13, 1918.

1 h-aZZ whom it may concern;

Be it known that I. Hnxm Comm, a subject of the Kingdom of lioumania, and resident of Paris, France, have invented certain new and useful Improvements in the Construction of Ti'agons, of which the following is a specification.

This invention relates to an improvement in the construction of rolling stockamore especially goods wagons and above all the construction of tank wagons.

The essential characteristic of the invention consists in the feature that the frame, the platform and the body or tank which together constitute the wagon are made of reinforced concrete so as to form a monolithic structure which otters a great resistance to stresses, is easy of upkeep and is unaffected by the weather and by variations in temperature.

One embodiment of the invention is illustrated by way of example in the accompanying drawings in which Figure l is a side elevation and Fig. 2 an end View of a tank wagon according to the invention. 7

In the practice of the invention there is first erected a metallic skeleton which constitutes at once the chassis or frame adapted to be mounted on wheels, the platform and the body or tank a of the wagon. Hangers b adjoining the metallic skeleton of the tank are arranged on each side of the latter so as to constitute brackets for suspension of the wagon on the springs c of the wheels of of the vehicle.

Internally or externally of the cylindrical skeleton a which is to form the tank proper are arranged metallic longitudinal beams c which are erected with the entire skeleton structure of which they form an integral or component part and which form the longitndinals ot the frame as also longitudinal rihs serving to connect all the other pieces of the metallic skeleton.

A dome f is fitted to the upper part of the wagon.

When the metallic skeleton is thus prepared, the concrete with or without centering is poured or placed thereon so as to constitute a monolithic structure of which all the parts are bound together.

tract-ion apparatus, battering, suspension etc, are embedded in the structure.

Externally the tank is reinforced at the end by one or more ribs 9' which form notchhoards on which may he rested the steps of a ladder-affording access to the upper part of the wagon. Internally of the wagon the said ribs g may he continued by longitndinai partitions adapted to resist any effort tend ing to effect longitudinal deformation of the tank a.

The advantages which this system of construction of wagon presents are as follows The construction is ri id and rapidly effected by a. process permitting of sturdardization, normal and easy and iner zpens in to carry out. Tank wagons thus erected are upkept without dili'iculty and easy of repair, if any fissure should he produced by any cause. They are adapted to transport ail kinds of liquids, such as Wines. alcohol, petrol, etc. without the latter being influenced by variation of temperature. These wagons may be readily washed by a jet of steam or water without leaving any taste or emanation of the product nzgeviously trans-- ported.

'lVith the object of simplifying the washing, the interior face of the wagon may he glazed byany suitable process.

The arrangements above described are be regarded only as exampl T he form, dimensions, details of execution and application may vary without departure from the invention.

Having now particularly described and ascertained the nature of my said invention and in what manner the same to he performed, I declare that what I claim is 1. A railway tank car con'iprising a siteleton frame, platform and tank all formed in reinforced concrete.

2. A railway tank car comprising a tank, platform and Wheel supporting brackets all formed of reinforced concrete.

3. A railway tank car comprising a tank, platform and Wheel supporting brackets all formed of reinforced concrete, spring connected to said brackets, and whee] support ing axles carried by said springs.
